Our Company

Established in 1993, Group One Builders Inc. is a build-to-suit luxury home construction firm based in Folsom, California. Owner Michael Robinson and his team have used their many years of combined hands-on design and construction experience to complete over 200 luxury home and remodel projects throughout the greater Sacramento area. They take a creative approach to problem solving, combining his excellent design sense with practical, real-world construction experience and an intimate knowledge of construction techniques, materials and cutting-edge products.

Building great homes begins with building great relationships. Building a great relationship starts with communication. Their commitment to the evolution and fine-tuning of the various systems used throughout the design and building process is rooted therein -- the constant improvement of communication. “Unlike the homes we build,” states Michael, “it’s a process that will never be complete – there is always something we can do better, and our entire staff is committed to continually looking for those things”. Group One’s systemized approach has been carefully designed to remove the stress from the decision making process -- structured enough to keep you focused, while flexible enough to avoid crowding your personal creativity. To work effectively, this must include everyone involved in the process, every client, subcontractor, supplier and staff member.

Michael Robinson and Ian Worley began their building careers as young tradesmen, learning and understanding the craft, both with a strong desire to excel at what they were doing. Michael grew up near Anchorage, Alaska, where his experiences as a framing carpenter, construction manager and general contractor formed the foundation of his vast knowledge and experience in residential building. His natural energy and drive eventually brought Michael and his family to California, where he put his diverse skills to work as general contractor in the Sacramento area.

Ian grew up in the Sacramento area, and found an early aptitude for design and woodworking, building musical instruments, furniture and cabinetry. He utilized these skills working as a finish carpenter, project manager and general contractor. Later Ian was lead designer for a custom home builder, studying architecture and design while strengthening his practical experience on the job.

In time, Michael and Ian found themselves looking for the opportunity to branch out and take their skills and experience to higher level. In April 1993 they founded Group One Builders, and set their sights on a simple common goal -- to excel at their craft. Through careful planning, Group One Builders has grown steadily in the years since, and the development and refinement of their various systems has continued as well. Now, many years later, they have well-established, long-term working relationships with a top-notch staff and a large network of quality subcontractors and suppliers. The entire process is approached as a team effort, and the continual development of these relationships is based on a common philosophy embracing mutual respect, pride and creativity.

At the end of 2013, Ian decided to go back to school at Berkley to finish up his degree in Architecture and focus solely on design. Michael purchased Ian’s stock in the Company and continued to carry on with the focus still on custom residential home and remodel projects. In 2016 his son Ben rejoined the Company as Field Operations Manager after several years living and managing construction projects in Texas.

on a System

There are many talented and creative tradespeople in the building industry, but the thing Michael recognized was the lack of focus and organization that caused so many to struggle. Not only were these talented builders and tradespeople struggling, but so were their clients, and it all seemed to stem from a simple lack of communication. The horror stories in the industry as a whole were far too common -- cost overruns, liens, poor quality control, and surprise after surprise. By always listening to the questions and uncertainties of their clients and others, identifying the issues and always seeking ways to improve the processes, these ideas have evolved into their unique and practical design/build system. Not a system that limits the flexibility and human interaction, but rather one that promotes it, by streamlining and providing a clear and understandable road map for the entire process. When we’re all reading the same map, we can always be on the same path.

The foundation to this system is rooted in education -- removing the mystery and doubt from a process that may be completely foreign to a client. This should be the first job of any design or building professional. Instead of shielding their clients from the intricacies of the process, empower them with knowledge. Group One seeks to educate their clients in the language of construction, while endeavoring to communicate in the language of the real world. The benefit for all is effective communication, and this the cornerstone of any successful relationship. The quality of the relationship between client and contractor, or contractor and subcontractor can spell the difference between an exciting and enjoyable building experience, and one you might rather have avoided. Communication within a clearly defined framework makes the process more efficient, less stressful -- an artful blend of the intimate attention to detail, and efficient, timely project scheduling and completion.

The same basic guidelines apply to most any situation, whether it is preparing a bid on your finished building plans, working with you as a team along with an Architect or Interior Designer, or working directly with you from the start on a complete design/build package -- detailed plans and specifications are the key. By clearly defining all the various materials, finishes and details, before we start, the possibility for misunderstandings is greatly reduced. This frees your mind (and ours) to focus on the important details and decisions that will ultimately define your unique home. Integral to our philosophy is this on-going commitment to communication, and to providing the highest quality personal service, and efficient, well-organized processes from design through completion. This starts with listening to you.

If our years of experience have taught us anything, it is that a happy customer is the only kind of customer to have. We feel very fortunate to have so many happy customers, and the ability to say that we truly love our jobs -- we really enjoy designing and building homes, and this is due in large part to the diverse experiences and personal relationships that have developed along the way.
